Constancia Smith has a brother Theophilus and his funeral booklet can be found at this site. ufdc.ufl.edu/CA01300446/00001. I believe Constancia's here as well.
I came across her when I was researching my own Smith line. My G - G Grandmother was Emily Dawson, she married a Edward Smith and had a brother William Hodge. They lived in Humptun's Ghut. There is also an additional connection, Constancia's sister, Emma Smith, married my Great Uncle Alfred Smith
